Independent third-party lab verification

Know what's actually in the vial.

We test every peptide batch on our own instruments for identity, purity, potency, heavy metals, endotoxins, and sterility. Passing batches receive a tamper-evident holographic serial that anyone can scan and confirm.

Pur3ity holographic verification seal with serial number

The seal counterfeiters can't fake

A shiny sticker is easy to copy. A serial that resolves to a real lab report on our database, and matches the vial in your hand, is not. The hologram makes tampering obvious; the serial makes the claim verifiable.

  • Unique serial linked to one specific batch report
  • Tamper-evident: peeling leaves a "VOID" mark

How a batch becomes verified

From the vial on a bench to a report you can scan, four steps, one serial number.

1

Sample intake

A sealed batch sample arrives and is logged against its lot number with a recorded chain of custody.

2

Lab testing

We run identity, purity, content, heavy-metal, endotoxin and sterility analysis on our own instruments.

3

Seal & serialize

Passing batches get a tamper-evident holographic seal carrying a unique serial tied to the report.

4

Scan to verify

Anyone scans the seal and lands on the exact batch report, confirming the vial matches its results.

What we test for

Each result below is reported per batch. We report the measured value against the brand's label claim.

Mass spec

Identity

Confirms the peptide is the molecule the label claims, by mass spectrometry.

HPLC

Purity %

Quantifies how much of the sample is the target peptide versus related impurities.

mg vs label

Potency / content

Measures actual milligrams of active peptide against the amount stated on the label.

ICP-MS

Lead & heavy metals

Screens for lead, arsenic, cadmium and mercury by inductively coupled plasma mass spec.

LAL

Endotoxins

Detects bacterial endotoxin levels using a Limulus amebocyte lysate (LAL) assay.

Culture

Sterility

Checks the batch for microbial growth under controlled culture conditions.

Visual

Appearance / form

Records the physical form, color and clarity of the lyophilized or reconstituted product.

What the seal stands on

Each verified batch is backed by the same independent process.

Why buyers ask for a Pur3ity serial

"We won't open a new supplier without a scannable batch report. Being able to pull the chromatogram from the serial settles the conversation in seconds."
Dr. Renee A.
Procurement lead, research lab (placeholder)
"Independent testing took the 'just trust us' out of our marketing. The seal does the talking, and our reorder rate moved with it."
Marcus K.
Founder, peptide brand (placeholder)
"For our intake checklist, a batch-traceable serial that resolves on Pur3ity's own site is non-negotiable. Photoshopped PDFs don't pass."

What a Pur3ity seal means, and what it doesn't

What it means

  • We tested a specific batch and published the measured results as of the test date.
  • The serial on the seal resolves to that batch's report on our own database.
  • The vial in your hand can be matched to the report it claims.

What it does not mean

  • It is not a guarantee of safety and makes no health or efficacy claim.
  • It is not an approval or endorsement by the FDA or any government agency.
  • Products referenced are intended for research use; always read the brand's own labeling.

Results are batch-specific and reflect the sample tested as of the date shown on each report. See Trust & Standards for details.
